Endstation ATM xBR Service Segmentation
and Reassembly Controller (ServiceSAR)
Conexant’s RS8235 offers endstations all of the xBR
service categories in a highly integrated 3.3V CMOS package.
The RS8235 architecture complements the RS8234 edge SAR
feature set, so that software reuse is maximized. The RS8235
directly connects to Conexant’s RS8251 PHY device for a total
NIC solution.
The RS8235 supports a similar feature set to the RS8234
edge SAR, but in a reduced footprint. System designers can
therefore offer a common traffic control and host interface
to a new market segment.
Integrated Management
The RS8235 complies with ATM Forum specifications UNI 3.1,
T.M. 4.1 and all other relevent standards. The RS8235 provides
integrated traffic management for all service categories, including
constant bit rate (CBR), variable bit rate (VBR1, VBR2, and VBR3),
real-time VBR, unspecified bit rate (UBR), available bit rate (ABR),
guaranteed frame rate (GFR) (guaranteed MCR on UBR VCCs),
and generic flow control (GFC). The xBR traffic management block
automatically schedules each VCC according to user-assigned
parameters to maximize line utilization.

... The host submits data for transmit by writing buffer descriptor pointers to one of four transmit queues. These entries may be thought of as task lists for the Endstation SAR to perform. In addition, the RS8235 can perform ATM server functions for up to four clients. The device’s architecture lessens the control burden on the ...

... The PCI interface between the host processor and the local system is controlled by the RS8235 Hardware Programming Interface (RS8235HPI), a software driver for the RS8235, on top of which a system designer can develop and place proprietary driver software. This interface allows users to easily port their applications to the RS8235/8251EVM ...
